About Dustcontrol Filter Units An extraction system should always be equipped with a filter unit. The filter unit separates coarse material in the cyclone body of the unit and fine dust in an internal arrangement of conical pleated cartridge filters. Pleated filters have very high filter areas in relation to their physical size. The filter units therefore have high capacity while maintaining compact overall dimensions. Filters are cleaned with reverse pulse which results in very effective cleaning, long filter life and low maintenance. Normally the filter units are equipped with a plastic sack for collection of the extracted material but other types of discharge arrangements can also be installed.

General In the filter unit, dust is separated from the air in several steps. – the cyclone will separate particles down to a size of 1/100 mm. – the filter will separate particles which go through the cyclone. The dust laden air is introduced into the cyclone at a high velocity. Through centrifugal force the dust particles, with higher relative mass than the air molecules, are forced outward toward the wall of the cyclone and fall toward the bottom. The air flows toward the centre of the cyclone and through the filter.

Filter Loading Permissible air-flow determines the air velocity through the filter material, known as filter loading. Consider also inlet/outlet velocities. Permissible filter loading varies with dust type.

120 120 160 120 120 60 60 60 60

Example: For the extraction of welding fume, the maximum permissible flow in the S 34000 will be: 60(m3/h)/m2 x 34 m2 filterarea = 2040 m3/h The velocity of the air through the inlet and outlet should not exceed 30 m/s. When one filter unit does not have sufficient capacity, several units can be connected in parallel.

The S 11000 filter unit is of modular construction and is therefore flexible in application. The inlet module can for example be both rotated and reversed. Additional module rings can be installed to increase the storage capacity of the cyclone. The S 11000 is either floor or wall mounted. The S 11000 and S 11000X must always be equipped with a discharge cone or other discharge arrangement. The X model is equipped with larger filter area and an extra module ring.

DC HEPA box Within the BioPharma, food processing, electronic, car and aerospace industries (just to name a few) there are numerous environments, which need extreme safeguards against dispersion of particles and aerosols. Here the DC HEPAbox enters the arena as a complimentary filtration with highest filtration level (>0.15 micro meter). DC HEPAbox has a robust design and withholds high negative pressure (40 kPa) which differentiates it from competing products. DC HEPAbox is even recommended to be used as a “police filter” between the filter unit and the vacuum producer in an ATEX environment. If for any reason the filter unit fails, the DC HEPAbox stops the dust from reaching the radial blower or turbo pump. In this way all standard vacuum producers can be used for ATEX applications, provided that the vacuum producer is placed outside an Atex zone. Part No Description 1180 DC HEPA box
